Rdm's use as a tank is on a mob that you can't melee. If it's melee-able then even if rdm had it's enmity generating abilities restored and even buffed to extreme leveles, it still wouldn't take the spot of the other tank jobs. You know why? Because if it's meleeable then you take a tank that can DD it while tanking to increase killspeed. Comparing Rdm tanking to war, drk, sam, mnk, nin, etc tanking is retarded.

No melee Rdm doesn't count.
